After that, revelation stopped coming to the Messenger of Allah (peace be upon him) for a while. This is related in the Messenger of Allah’s saying, «Then revelation stopped coming to me for a while» [related by Al-Bukhari]. But the Messenger of Allah (peace be upon him) did not mention how long this time was, so the historians differ on this point. Ibn Saad reported from Ibn Abbas that it was a few days [Fat-h Al-Bari].
Maybe the reason Allah (Glorified is He) stopped sending revelation was to alleviate the Messenger of Allah’s fears and for him to overcome the feelings he had experienced at first [Fat-h Al-Bari].
The Messenger of Allah (peace be upon him) became sure about the reality of the announcement he had received, and he became sure that he was now a prophet of Allah and that the one who brought the revelation brought news from heaven. And when his waiting and longing for news from heaven to come would result in him becoming steadfast and self-possessed upon the arrival of any revelation, Gibrael (peace be upon him) came a second time [adapted from The Sealed Nectar].
